Palynological Data for Otway Basin Petroleum Wells

Over 200 new palynological samples were collected from 14 selected Otway Basin wells, with revised data provided for 18 additional wells. The dataset contains consultant reports and standardized CSV data files resulting from a collaborative 2002-2004 project by Geoscience Australia, PIRSA, and DPI Victoria. It was created to enhance the petroleum prospectivity of the basin through improved biostratigraphic age-control and correlation.

Use Cases

• Correlate stratigraphic units across wells using standardized palynological taxonomy for basin-wide chronostratigraphic framework construction.
• Refine biozonations and age-control for petroleum systems analysis by integrating new sample data with revised historical reports.
• Analyze depositional systems through palynological data to assess petroleum prospectivity in the Otway Basin.
• Perform quality-assurance on palynological synonyms and systematics by comparing original consultant reports with updated CSV files.

Strengths

• Includes data from over 200 new physical samples, providing substantial primary observations.
• Covers 32 distinct Otway Basin wells (14 with new samples, 18 with revised data) for regional coverage.
• Data has been standardized to a consistent taxonomy in current use at Geoscience Australia, improving comparability.

Limitations

• Core data formats (WMF, DEX) are legacy and may require specialized tools or conversion for modern analysis.
• The dataset is static, representing a 2002-2004 project snapshot with no ongoing updates planned.
• Sample distribution across 32 wells may not provide uniform spatial or stratigraphic coverage of the entire basin.
